“…A large amount of material was brought into the lake and later re-deposited in the steep slope area, where the inclination is more than 14% (Fig. 2b) or at sites with greater exposition to the prevailing wind directions (Punning et al, 2004). This may cause also redeposition of macrofossils.…”

Surveys and mapping of macrophyte vegetation and its remains in the surface sediments of two Estonian lakes demonstrate that about 50% of the submerged and floating-leaved plants growing in the lake are represented as macrofossils in the sediment. Only one third of the helophyte taxa were found in the sediment, and they had a very limited distribution close to their growing place. Part of the macrofossils, such as fragments of Nymphaea alba seeds, were distributed over the entire lake bed and were not connected with the actual growing place. The bottom topography of the lake affects the distribution of macrofossils.

“…The northern part of the lake is shallow with a mean depth of 1-2 m. It forms a relatively separate system from which matter fluxes to other parts of the lake are apparently not very large (Punning et al, 2004). The smallest slope inclinations in the south-western part of L. Viitna occur at depths of 4-5 m (Fig.…”

“…Comparison of the fluctuations in the water level in some Estonian lakes with the lithological composition of the sediment, P content, carbon and nitrogen ratio, fossil pigments and diatom communities showed that in medium-term time scale (10 3 years) the decisive factor in the trophy of the lake was the depth of the water column above the sediment (Punning et al, 2004).…”

“…Less attention has been paid to sedimentary processes, especially to the grain size of lake sediments; however, these studies have been promising in investigating lake-level variations in small temperate lakes (Digerfeldt, 1986;Punning, Alliksaar, Terasmaa, & Jevrejeva, 2004). …”

Lithological and granulometric investigations of the surface and short core sediments in L. Martiska (northeastern Estonia) showed that variations in the grain-size parameters and LOI content were influenced by the changes in deposition conditions during the regression and transgression phases monitored in the lake since the 1960s. During the regression and transgression phases displacement of the erosion-transport-accumulation zones in the lake took place depending on the bottom topography. The water level fluctuations are especially clearly reflected in grain-size variations in cores from peripherial area.

A multi-indicator paleolimnological study of sediments from Lake Ķūži (central Latvia) was used to obtain a comprehensive record of environmental changes in the Holocene. Periodicity in the changes and the main drivers (lake basin development, catchment properties, climate, human activities) of the sedimentary record was studied. In order to comprehend the whole-lake sedimentation during the Holocene, a detailed multiindicator record from the central part of the lake was integrated with records of sediment mass accumulation rates from four cores from different parts of the lake and a GPR (ground-penetrating radar) survey of the lake basin. The observed changes in the sedimentation regime that took place during the early Holocene are strongly linked with variations in climatic conditions, but the catchment and lake basin also played an important role. In the middle Holocene the water level was stable and the lake was influenced by climate mediated through changes in the catchment vegetation. Around 5 000 cal. BP sedimentation pattern changed, and three of the four main drivers made a comparably strong impact on the sedimentary signal. Since 2 000 cal. BP multiple indicators point to a major disturbance clearly related to human activity, which conceals the impact of the natural drivers.
